. .4 Claims.

This invention relates topaper calendering machines and in its more specific aspects is directed'to a paper strip feeding or guide means for the calendering machine;

The object of the invention is to'provide a series of feed or guide mechanisms for'calendering machines which will enable the paper stock to be threaded through the-machinegwithout manual attention after being manually threaded into the first pass in the calendering machine. I

In the drawings:

Fig. 1 is a front elevational view of a calendering machine incorporating the invention;

Fig. 2 is a sectional view taken substantially along the line 2-2 of Fig. 1;

Fig. 3 is a view taken along the line 33 of Fig. 2 to illustrate the feed-and guide mechanism compression adjusting mean 7 Fig. 4 is a view similar to'Fig; 3 but with the feed and guide mechanism compression adjusting mechanism in a different position of'adjustment; and

Fig. 5 is an enlarged sectional view of two of the rolls shown in Fig. 2 and associated feed and guide mechanism.

Referring now to the drawings, numerals I and 2 designate the upright members and 3 and 4 designate the base and top members, respectively, of a calendering roll stand frame; A series of calendering rollers 5, 6, 1, 8, and 9 are rotatably mounted therein and are arranged one above the other, as illustrated. The rollers are provided with suitable spindles that are suitably journaled in the uprights l and 2. The roller 9 has a pulley l secured to one of its spindles by means of which roller 9 and all others are frictionally rotated. A pair f calendering roller pressure adjustment members II and I2 is disposed between roller and top member 4 in order that the several rollers will be urged into engagement with each other and the stock Worked on at a predetermined pressure.

The paper stock I3 is threaded about roll 5, then through the pass between rollers 5 and 6 PATENT-T OFFICE,

and finally emerges from the last pass between rollers 8 and 9. The stock gagement with each roller between passes so that it will be threaded into the several passes ','.with out manual assistance. It is, however, threaded manually between guide mechanism l4 and roller 5 and it enters the first pass between rollers 5 and 6 without further assistance. The succeeding guide mechanisms [5, l6, and I! are positioned opposite rollers 6, 1, and 9, respectivemember of each ly, as illustrated, to guide the stock I 3 into-the passes between the several rollers. I

Each of the guide mechanisms comprises a pair of end frame members l8 and I9 and aback 20preferably integrally associated with the end members to'connect' and space them. The free Or unsupported ends'of members I 8'and l9 are contoured generally-to theshape of the calendering rollers 5-8. A plurality of rollers 2 I, 22, 23, etc., are rotatably arranged in the free ends of members [8 and I9 and are engageable with the calendering rollers.- These rollers are spaced sufiiciently close together so that stock l3 will be kept in engagement with the several calendering rollers. relatively small'in diameter and circumscribe substantially degrees of the calendering roll surface.

. Compression is 24 rotatably mounted in base 3 at its lower end and its upper end is rotatably for each back-up member, is mounted 24 and a handle 24 is secured to the shaft by means of which it is rotated. When shaft 24 isrotated-to the position '01 Fig. 3, the guide mechanisms tightly engage the respective calendering rollers 6 and 8 and when rotated to the Fig. 4 position, they are disengaged therefrom. The other guide mechanisms l4 and I6 disposed opposite calendering rollers 5 and I are moved by a shaft 30 whose upper end is rotatably supported in top member 4 and Whose lower end is rotatably supported in a bracket 3| secured to uprights l and 2. The feed mechanisms have back-up members 32 and 33 adjustably supported on studs 34a threaded into, uprights l and 2 and are urged outwardlyby springs 34 against the nuts on studs 34a.

on shaft the back-up members 32 and 33,

is employed to rotate the cams 35 and 36 to the two positions illustrated Rollers 2|, 22, and 23-arein Fig. 3 for the same purpose as discussed in connection with guide devices l5 and H.

An auxiliary member 31 in the form of a plate is resiliently supported on each guide member and whose lower end is pointed or knife edged is in engagement with the calendering roller disposed immediatelyabove it so that the paper stock will be stripped from the calendering roller and guided between the roller H of the mechanism with which the guide 31 is associated. In the particular construction shown, the plate member 31 has at its inner end a depending flange 31 adapted to bear against the outer side face of the upper marginal part of the back member 20 of the frame of the guide mechanism, said flange being provided with a small slot 31 through which extends a bolt 39; extends through an aperture in the back member 20 and has a nut 40 on the inner end portion thereof engaging the inner side face of the back' member 20, a coiled expansion spring 4| being interposed between the head of the bolt 39 and the outer face of the flange 3! so that the plate member 3'! is supported for pivotal movement on the back plate 20 of the frame and is urged by said spring into engagement with the calender roll. Water trough 38 is positioned under each guide or feed member in the manner illustrated to collect-water draining from the calendering rollers.
